Define x :
-----------------------------------------------
Let the width be x
Width = x
Length = 4x + 7
-----------------------------------------------
Formula :
-----------------------------------------------
Perimeter = 2 (Length + Width)
Perimeter = 74
2(4x + 7 + x) = 74 // sub length and width into the equation
2(5x + 7) = 74 // combine like terms
10x + 14 = 74 // Apply distributive property
10x = 60 // Take away 14 from both sides
x = 6 // Divide by 10 on both sides
-----------------------------------------------
Find Length and Width :
-----------------------------------------------
Width = x = 6mm
Length = 4x + 7 = 4(6) + 7 = 31mm
----------------------------------------------------------------------------------------------
Answer: The length is 31mm and its width 6mm.

Answer:
2 units right and 3 units up. just took the test this is VERY correct
To find how much they earned in one hour you need to 62/4= 15.5 which means they earned 15.5 an hour. Next do 15.5*6=93. Finally 155/15.5=10
Answer:
F = 6
Step-by-step explanation:
find the constant of variation (k) first by using this formula:
f = k/d
plug in given info to find k: 3 = k/4 so k = 12
use 12 to find F: F = 12/2
